Haruka collects shining things: marbles, pieces of glass, scraps of metal, anything. He pockets them without thinking, and then hides them wherever he can around his room.
Kantarou finds him polishing a marble liberated from a ramune bottle and leans over his shoulder. “Tengu really are like crows, aren’t they?” he asks, and takes it from Haruka’s fingers. He holds it to the light and smiles at the sparks it creates. “Ah, pretty.”
The sunlight catches in his eyes, so they look wider than normal. Haruka has yet to find anything in that particular color.
He’ll have to keep looking.
